摘要:A method for microencapsulation of substances is provided. The substance(s)is/are dissolved or dispersed in an organic solvent of the kind that is partially miscible inwater media. This organic solution is then mixed with an aqueous solution, which issaturated with an organic solvent and an emulsifier to form an emulsion. The emulsion isthen poured into water under continuous agitation for the extraction of residual solvent.The formation of the solid capsules takes place during this extraction process. Thecapsules are undergone to further purification, whereby the microcapsules can beseparated from the water and dried. By conditions of incubation of microcapsules inwater-containing formulations the wall-softening process takes place. The unique systemfor controlled releasing the ingredients from microcapsules is based on the above-mentioned process.
